* Terrorblade starts out with and gains a lot of armor from his agility growth. His illusions also make it difficult for Slardar to focus down the real Terrorblade.
* Terrorblade can use
Sunder to save his allies who are Doomed.
* Wraith King has three passive abilities and only a single active ability, so Doom does not hinder him significantly.
* Doom expires upon death, so it is effectively removed after Reincarnation activates.
Additional:
* Even if he is Doomed, Wraith King can tear down Doom with physical attacks, and can still reincarnate as long as it is off-cooldown.
* Fire Spirits greatly reduces Slardar's already low starting attack speed (which Bash of the Deep relies on), making the laning phase very hard for him and discouraging Slardar from aggressively threatening lane kills.
* Supernova, ignoring Phoenix's lack of armor and Slardar's high damage single hits, is extremely hard for Slardar to take down on his own, especially after being hit by Fire Spirits.
* Icarus Dive is one of the longest distance escape spells in the game, and can help a good Phoenix escape from Slardar before he gets a
Blink Dagger. However, the high cooldown means Phoenix is vulnerable to backstabs from any roamers after said spell is used.
* Slardar can interrupt an Icarus Dive from completing the flight with both of his stuns, however, likely leading to death if Supernova is on cooldown.
* A lot of the items a Phoenix builds throughout the game naturally counter Slardar. Shiva's Guard,
Heaven's Halberd and
Eul's Scepter of Divinity all stall Slardar's normal attacks in some way, while
Spirit Vessel's percentage-based damage is good against his innate durability.
* Medusa cares less than other heroes about armor reduction, since
Mana Shield blocks 70% of all damage without taking armor/magic resistance into consideration. This makes 60% of your Corrosive Haze ineffective until Medusa's mana is drained.
* Doom does not disable Mana Shield. As such, Doom's damage is largely mitigated by her mana shield. Additionally, Medusa is not reliant on her abilities to be effective during a teamfight, making Medusa an unproductive hero to target.
* Medusa is an ideal Linken's Sphere carrier. Should one be purchased, and without any additional disables, Doom may find that few opportunities exist to effectively lockdown, disable, and kill Medusa.
* Other heroes who has armor and slow debuffs won't allow Medusa to disengage from combat: Tidehunter,
Bristleback,
Slardar.
* Drow Ranger can be difficult to get on top of, thanks to her Frost Arrows and
Gust. With these two abilities, Drow Ranger is able to effectively 'kite' Doom and minimize his impact during team fights and laning stage.
* Much of Drow Ranger's effectiveness comes from her passive Marksmanship, which is not disabled by Doom.
* Whenever Doom casts his ultimate, Centaur Warrunner can cast Stampede and allow the Doomed hero to run away, wasting Doom's ultimate.
Additional:
* Stampede can be used to free an ally from the grasp of Doom. Without any means of effective lockdown, kills can be difficult to secure when against an enemy Centaur Warrunner. Also, Centaur's tendency to have lots of health and HP regen tend to help counter Doom.
* Slardar has high priority on building moblity items such as Blink Dagger rather than tank items. Zeus can easily deal large amount of damage to him if not caught out of position first.
* Due to Doom's naturally high health, strength gain and common itemization for durability, Heartstopper Aura is particularly effective. The health loss is also large enough that, throughout all stages of the game, the aura effectively neuters the health regeneration granted by Devour.
* Necrophos can help to keep both himself and his allies alive during Doom through his natural regeneration granted by Heartstopper Aura (which is not disabled by Doom), or in the case of an ally, through his
Death Pulse. Additionally, Necrophos is an ideal
Mekansm carrier. Should one be bought, kills against Necrophos' team can be difficult to secure due to the damage-over-time nature of Doom and his abilities.
* Doom typically wants to be a hero that soaks attention from the enemy team and takes the role of an initiator and disabler. As such, Doom is an ideal target for Reaper's Scythe, as it is likely Doom will be at the fore-front of any fight.
* Doom generally does not impede Sven in almost any way, provided he has activated God's Strength beforehand.
* The slow applied from Corrosive Skin offsets the movement speed bonus granted by Scorched Earth and the tick-based damage from Infernal Blade and Doom will continually slow Doom down. This allows Viper, much like Sniper, to 'kite' Doom and keep him at a safe distance between the two. Additionally,
Corrosive Skin applies an attack-speed slow which is fairly crippling to a hero such as Doom that, naturally, has a high base attack-time, poor agility gain and builds little attack-speed items.
* Since Doom does not disable auto-cast abilities, Viper's Poison Attack will continue to work. Doom may find it hard to close the distance between himself and Viper, and thusly difficult to effectively lockdown and continually deal damage through his abilities.
* Illusion heroes like the aforementioned Phantom Lancer or
Naga Siren, or heroes that tend to buy
Manta Style, like
Luna or
Juggernaut, will give Slardar a hard time, as his damage is single-targeted.
* Heroes who often build Linken's Sphere:
Weaver,
Morphling,
Medusa.
* Heroes with a slow attack rate will find themselves struggling to take out Tombstone, like Doom.
* Heroes with low mana pools (eg.Doom and
Tidehunter) will feel the effects of Silencer's Intelligence Steal far more than others.
* Bloodseeker's
Rupture forces Slardar to stay still during fights, preventing Slardar from using Guardian sprint to move in and out of fights. This takes away the ability to initiate and re-initiate with Slithereen Crush's low cooldown. Due to the increased move speed from Guardian Sprint, Slardar can lose health at about 160% the rate of normal heroes while under
Rupture. Bloodseeker's
Thirst also gives him enough move speed so that he's one of the few heroes who can outrun or catch up to a Slardar during Guardian Sprint.
* Single-target disablers will have difficulty locking down a Chaos Knight with Phantasm active: Bane,
Beastmaster,
Bloodseeker,
Clockwerk,
Doom,
Shadow Shaman.
* Heroes who can disable Mars but cannot do any damage to him, meaning he just tanks their abilities: Doom,
Magnus.
* Illusion heroes like the aforementioned Phantom Lancer or
Naga Siren, or heroes that tend to buy
Manta Style, like
Luna or
Juggernaut, will give Slardar a hard time, as his damage is single-targeted.
* Fortune's End applies a basic dispel which can be used to dispel Corrosive Haze, or even Slardar's own Guardian Sprint.
* False Promise is able to dispel Corrosive Haze and Slithereen Crush stun/slow from any allies Oracle chooses to cast it on.
* Fate's Edict can also be cast on Slardar to prevent him from proccing his Bash of the Deep.
* Heroes with the ability to heal allies will not be able to heal heroes affected by Doom:
Chen,
Dazzle,
Io,
Oracle,
Omniknight,
Witch Doctor,
Winter Wyvern,
Abaddon, etc.
* Feast deals damage and heals Lifestealer based on the target's maximum HP, which is greatly effective against naturally high HP heroes such as Doom.
* Rage allows Lifestealer to become spell immune to negate the magical damage of Infernal Blade and Scorched Earth.
* Doom has no effective means of escape from Open Wounds and
Ghoul Frenzy. This is particularly devastating in the laning stage, where Doom may have to play a much more passive, conservative play style as a result.
* Heroes with high physical damage can damage Lifestealer more than he can heal: Bristleback,
Clinkz,
Luna,
Shadow Fiend,
Slardar,
Terrorblade
* Lone Druid is essentially two heroes. Dooming one over the other still leaves Lone Druid or his bear able to do their job during a fight. Additionally, Lone Druid is not hindered as much as other heroes by the silence and mute of Doom since the hero relies more on attacks than abilities.
Additional:
* Doom will be very hestitant to use Doom on the Spirit Bear, and using it on Lone Druid himself will not stop the bear from attacking him especially if True Form has already been used.
* Devour does not work on the Spirit Bear and pushes the lane so Lone Druid can safely farm under tower.
* Besides Lone Druid and
Meepo, Doom is potentially good versus every hero since Doom will render any hero helpless for up to 16 seconds. This is particularly true for fragile heroes that heavily rely on mobility to stay alive.
* While Slardar has Guardian's Sprint activated, Powershot cannot slow him and is easier to avoid.
* Slithereen Crush and Bash of the Deep help Slardar put Windranger in place, even when she uses Windrun to escape.
* Corrosive Haze from Slardar is very effective against Windranger's already low armor. This becomes even worse if she has Aghanim's Scepter-upgraded
Windrun, because it also reveals her position and allowing his allies to use their abilities on Windranger.
* Note that the invisibility provided by Aghanim's Scepter-upgraded
Windrun is not broken upon attacking, casting abilities or using items, so it's vital to cast Corrosive Haze beforehand.
* Doom completely takes Windranger out of a team fight, a hero who relies heavily on using abilities and items to contribute in team fights.
Additional:
* Doom completely takes Windranger out of a team fight, a hero who relies heavily on using abilities and items to contribute in team fights.
* Shadow Fiend, a normal Shadow Blade builder often relies on its invisibility to escape fights. Corrosive Haze reveals Shadow Fiend and also weakens his already low armor.
* Doom has several disable abilities to choose from jungle creeps (e.g. War Stomp,
Ensnare) to deal with Shadow Fiend who lacks escape abilities.
* When Doom combines creep abilities with Scorched Earth,
Infernal Blade, and
Doom, Shadow Fiend most likely will die as he cannot use Shadowraze and Requiem of Souls to protect himself, and also cannot even flee by using
Shadow Blade or
Blink Dagger.
* Although Shadow Fiend has a high physical damage output, Doom has a large health pool to survive it, meaning Doom's combo with high magical damage output will shutdown Shadow Fiend first.
* Doom usually buys Radiance to improve his damage, making his nuke combo more deadly to Shadow Fiend. The blind also prevents Shadow Fiend from landing his attacks often.
* Corrosive Haze reveals Pudge's location, making it hard for him to use Meat Hook from the fog of war on Slardar's teammates or Slardar himself.
* Slithereen Crush interrupts Pudge while he is using Dismember.
* Guardian Sprint allows Slardar to avoid Meat Hook.
Additional:
* While Slardar has Guardian Sprint activated, Rot cannot slow him and
Meat Hook is easier to avoid.
* Slithereen Crush allows Slardar to interrupt Dismember at close range (when Slardar is not a target).
* Corrosive Haze reveals Pudge's location, making it very difficult for him to land hooks from the fog.
* Infernal Blade deals high damage to Pudge due to his scaling health and strength gain from
Flesh Heap.
* Using Doom with timing against Pudge who had just activated
Rot would usually kill him.
Additional:
* Doom disables the toggling of Rot and, if cast at the right time, may leave Pudge with a potentially lethal health drain.
* Doom's naturally high health, strength gain and damage output makes him a poor target for Pudge.
* The damage of Doom's Infernal Blade scales with the target's maximum health, which is particularly effective against Pudge due to his naturally high health and further health granted by stacks of Flesh Heap.
* The brutal physical damage of Slithereen Crush and
Bash of the Deep can quickly remove Void Spirit's shield and stun him for a while.
* Corrosive Haze provides vision of Void Spirit while he is running away and
Guardian Sprint allows Slardar to quickly close the gap
* Doom is effective against every hero, and Void Spirit is no exception. Being unable to cast spells or items during fights for 16 seconds nullifies his impact entirely.
* Doom has a very versatile build and can consume creeps which has abilities that can stun or provide additional magic resistance.
* Doom's high strength gain and versatility in items can be effective against Void Spirit's magical damage.
* Guardian Sprint allows Slardar to outrun Bristleback, even when slowed by Viscous Nasal Goo.
* Corrosive Haze's armor reduction makes Bristleback much less tanky.
* Infernal Blade deals scaling damage and is useful against high health targets such as Bristleback.
* Doom disables Bristleback's low cooldown abilities, preventing him from triggering Warpath. With his upgraded level 25 talent, it also breaks Bristleback's passive, rendering him more vulnerable.
Additional:
* Infernal Blade deals scaling damage and is useful against high HP targets such as Bristleback.
* Doom prevents Bristleback from casting his two low cooldown abilities, which then prevents him from utilizing
Warpath.
* If Doom chooses the Level 25 talent {ValueColor:1|Doom applies Break|25tal} {Symbol:Talent}, he can disable Bristleback and
Warpath, taking away much of his durability and damage potential in team fights.
* Slardar can reveal Clinkz with Corrosive Haze and make him easy to kill, and his
Bash of the Deep also hits hard against Clinkz's naturally low health pool.
* Slardar's Guardian Sprint can catch up with Clinkz's Skeleton Walk.
* The stun and slow from Slardar's Slithereen Crush can hold Clinkz in place.
Additional:
* Clinkz survivability depends entirely on Skeleton Walk. Corrosive Haze not only makes its invisibility useless, but also makes Clinkz even more vulnerable to physical damage.
* Scorched Earth deals damage to Clinkz during Skeleton Walk.
* Doom shuts down Clinkz entirely, as it prevents him from casting any of his spells and contributing a large amount of damage in teamfights.
* Corrosive Haze hinders Nyx Assassin's ganking attempts with
Vendetta, as well as reducing his armor and make him very vulnerable due to his low health pool.
* Guardian Sprint allows Slardar to catch up with Nyx Asssassin and finish him off if he has vision over him.
* A well-timed Doom prevents Nyx Assassin escaping with Vendetta and fighting back with
Spiked Carapace.
* Doom's high health also allows him to easily shrug off Nyx Assassin's burst damage and fend him off.
* Slardar deals entirely physical damage. He does not have to worry about Counterspell.
* Slithereen Crush and
Bash of the Deep prevent Anti-Mage from using Blink, the latter even if Anti-Mage activates
Black King Bar.
* Corrosive Haze allows allies to take down Anti-Mage before he has a chance to Blink, and maintains vision over him even if he does Blink away.
Additional:
* Slithereen Crush and Bash of the Deep deals physical damage, bypassing the magic resistance bonus from Counterspell
* Corrosize Haze significantly increases the damage dealt against Anti-Mage, and makes it harder for him to flee with Blink, although Anti-mage can block its casting with with Counterspell
* Doom shuts down Anti-Mage's escape capabilities with Blink. The ability also deals pure damage, which ignores the protection from Counterspell.
* However, a well-timed Counterspell can reflect it back.
* If Doom has Aghanim's Scepter,
Doom can break Mana Break and Counterspell, weakening both his offense and defense.
* Doom's low mana pool causes him to take little damage from Mana Void.
Additional:
* Doom prevents Anti-Mage from maneuvering around a fight or escaping from an initiation using
Blink. Additionally, Doom deals pure damage, which is not affected by
Counterspell. This can quickly whittle away Anti-Mage's naturally poor health pool.
* However, Doom must be careful when using Doom as a well-timed
Counterspell can block and reflect it back against Doom himself.
* The Level 25 talent {ValueColor:1|Doom applies Break|25tal} {Symbol:Talent} will also disable Mana Break and
Counterspell's passive component, which makes Anti-Mage significantly less effective in fights and more susceptible to the high magical damage of Doom's abilities and his allies.
* Heroes who can provide True Sight or semi-reveal enemy heroes as Nature's Prophet is prone to buying Shadow Blade:
Bounty Hunter,
Slardar,
Spectre,
Zeus,
Spirit Breaker.
* Doom can eats Nature's Prophet's treants with Devour and gains lots of gold.
* Doom can buy Radiance or use his
Scorched Earth to quickly wipe out a swarm of Treants.
* Doom and a ministun from
Infernal Blade's prevents Nature's Prophet from escaping with Sprout and Teleportation.
* Crystal Maiden's already low armor and easily interruptible ultimate,
Freezing Field can make Slardar her worst nightmare.
Crystal Maiden also often builds
Glimmer Cape which is revealed by Corrosive Haze.
* Doom alone can easily pick off Crystal Maiden since she is fairly fragile, even with using only basic attacks, Infernal Blade, and
Scorched Earth.
* Doom prevents her from using any abilities in a fight, making her impact negligible.
* Devour allows Doom to acquire a stun, allowing him to cancel Freezing Field without having to use
Doom.
* Slardar's
Slithereen Crush allows him to stun Spectre and illusions, and
Corrosive Haze prevents her from juking with
Spectral Dagger.
* Infernal Blade's damage is calculated by percentage of maximum health. Since Spectre is usually tanky, it will hurt her more than most normal attacks.
* Doom can take out Spectre out of a teamfight completely. When combined with the level 25 talent {ValueColor:1|Doom applies Break|25tal} {Symbol:Talent}, it will disable both
Desolate and
Dispersion, taking away her extra damage and durability.
Additional:
* Infernal Blade's damage is calculated by percentage of maximum health, meaning that it will hurt Spectre more than most normal attacks, negating some of her tankiness.
* Doom can pick up several different abilities from neutral creeps using Devour, some of which can be annoying to Spectre.
* Mud Golem, Dark Troll Summoner, Harpy Stormcrafter, Satyr Mindstealer or Satyr Tormenter are good examples.
* Doom makes Spectre less disruptive. Combined with
Aghanim's Scepter, it will disable Spectre passive skills, reducing her potential in teamfights.
* Heroes with spells that negate invisibility such as Bounty Hunter,
Zeus and
Slardar prevent her from saving her allies with Moonlight Shadow.
* Doom completely takes Mirana out of a team fight, a hero who relies heavily on using abilities and items to contribute in team fights.
* Bounty Hunter and
Slardar both have ultimates (
Corrosive Haze and
Track) that reveal Invoker through Ghost Walk.
* Doom completely takes Invoker out of a team fight, a hero who relies heavily on using abilities and items to contribute in team fights.
Additional:
* Doom is a good way to shut down Invoker, preventing from casting spells and using items for a lengthy time, thus forcing him to invest on
Linken's Sphere.
* Corrosive Haze and
Bash of the Deep will make short work of Huskar's low armor, even if Slardar is alone.
* Doom with the {ValueColor:1|Doom applies Break|25tal} {Symbol:Talent} talent can be useful against heroes with troublesome passive skills while also disabling them for a long time:
Phantom Assassin,
Enchantress,
Huskar,
Underlord.
* Heroes with armor reducing abilities greatly hinder Visage's defense like Slardar and
Dazzle.
* Scorched Earth can be used to engage Visage while removing Gravekeeper's Cloak charges.
* Infernal Blade will deal tremendous amounts of damage over time due to Visage's high health pool.
* Doom completely nullifies Gravekeeper's Cloak and prevents Visage from casting spells.
* High health heroes (Axe,
Doom) fall fast with Fury Swipes stacks.
* Slardar is one of the few meele heroes who can lane against Ursa in the early game, out harassing him with Bash of the Deep, and running away from a bad engagement with Guardian Sprint
* Corrosize Haze can force Ursa to cast Enrage defensively instead of offensively
* With Corrosize Haze, Slardar's team can quickly dispatch of Roshan, denying one of Ursa's greatest advantages
* Doom makes Ursa less disruptive, and it cannot be dispelled with Enrage upgraded with
Aghanim's Scepter.
* Slardar's level 25 talent makes
Corrosive Haze undispellable, thus providing his allies vision of Slark.
* Heroes with silencing abilities can be particularly deadly when Slark is trying to escape: Silencer,
Death Prophet,
Puck,
Doom.
* Heroes who can provide True Sight are always credible threats: Slardar,
Bounty Hunter, especially
Zeus since his
Lightning Bolt provides True Sight without the need to detect her beforehand to apply the debuff. So even a late-coming Zeus can easily scout a large area to reveal her, and she cannot purge herself from his sight with the dispel talent.
* Weak damage but high tick rate or persist in a long time: Slark,
Gyrocopter,
Queen of Pain,
Shadow Shaman (
Shackles),
Jakiro,
Pugna,
Doom
* Heroes that can quickly deal damage to her, regardless of how weak they are, can easily break through her Refraction:
* Multiple attackers thanks to summoned units or clones: Meepo,
Witch Doctor,
Lycan,
Enigma,
Shadow Shaman
* Multiple attackers thanks to illusions: Phantom Lancer,
Chaos Knight,
Naga Siren (bonus for her
Ensnare). Also despite the visual effects, Templar Assassin does not spill damage against illusions or buildings, so she is not a really good hero to clean up illusions.
* Weak damage but high tick rate or persist in a long time: Slark,
Gyrocopter,
Queen of Pain,
Shadow Shaman (
Shackles),
Jakiro,
Pugna,
Doom
* Doom can easily kill Chen's creeps and obtain their abilities with Devour.
* Scorched Earth's area-of-effect can clear multiple of Chen's creeps at once.
* Doom renders Chen completely helpless, and unable to save himself or his allies with
Hand of God.
Aghanim's Scepter upgraded
Doom also allows Doom to cast
Doom on himself and disable both, Chen and his creeps around him.
* Infernal Blade deals scaling damage and is useful against high HP targets such as Timbersaw.
* Timbersaw is extremely reliant on his abilities to be effective during a team fight - both for mobility, damage and crowd control. Timbersaw offers very little, impactful right-click damage, and thus Doom is particularly crippling against him.
* Additionally, when Doom chooses the {ValueColor:1|Doom applies Break|25tal} {Symbol:Talent} talent, Doom disables
Reactive Armor, which effectively removes the durability which Timbersaw is commonly known for.
Additional:
* Doom shuts down Timbersaw completely, negating his mobility and preventing him from doing any damage. It also breaks Reactive Armor's passive bonuses from
Aghanim's Scepter.
* Infernal Blade can stun Timbersaw several times in a fight, potentially interrupting Timber Chain. Also it's useful since Timbersaw has high HP due to the damage scales based on max HP.
* Doom prevents Storm Spirit from using all of his abilities and items, rendering Storm Spirit useless in a fight.
* Corrosive Haze works much like
Track, giving the enemy team vision over Riki. While it doesn't give a movement speed or gold bonus, it instead can melt Riki's armor and Slardar can use
Guardian Sprint to catch up to him.
* Slardar's Aghanim's Shard, causes
Slithereen Crush to apply Corrosive Haze even if Slardar does not have vision over him.
Additional:
* Corrosive Haze makes Riki completely vulnerable to Slardar and his allies, as Riki has no easy way of dispelling it.
* Slardar's physical damage with Slithereen Crush and Bash of the Deep amplified by Corrosive Haze can easily kill Riki.
* Faceless Void relies on Time Walk for mobility and survivability but he can be prevented from utilizing it through
Doom.
* Doom has a high cooldown duration for every ability except Infernal Blade, so he is not significantly affected by Time Dilation.
* Corrosive Haze will reveal Treant Protector even when he is under the effects of Nature's Guise.
* Ember Spirit cannot use his Activate Fire Remnant to escape while affected by
Doom.
* Doom can stop Death Prophet from casting spells, which makes her useless during team fights if she didn't cast Exorcism before the fight, and also nullifies healing from Exorcism and Spirit Syphon. Furthermore, Doom can use
Scorched Earth to chase after her.
* Arc Warden relies on items and abilities, as well as his Tempest Double, to deal damage to enemies.
Doom effectively denies that and makes Arc Warden useless in fights.
* Doom makes Ogre Magi less disruptive.
* Infernal Blade effectively negates Ogre Magi's durability.
* With Aghanim's Scepter, he can disable Multicast.
* Doom's low armor makes him weak against Alchemist's high physical damage output.
* Corrosive Haze followed by
Slithereen Crush takes advantage of Alchemist's main weakness, being physical damage before he has the change to improve his surviability with items.
* Bash of the Deep will deal lots of damage during the laning phase.
* Doom can disable
Chemical Rage's increased healing, rendering Alchemist helpless against Doom.
* Attacks from Infernal Blade can deal serious damage to Alchemist as it deals damage based on the hero's maximum health.
* Doom is generally tanky and has naturally high health, allowing him to survive Puck's onslaught in any stage of the game.
* His namesake ultimate Doom is one of the best solutions to counter Puck, as it will silence Puck for a lengthy duration. A Puck silenced for more than 3 seconds usually ends up dead.
* In addition, if Doom chooses the Level 25 talent Doom applies Mute, Puck will not be able to use items altogether, most especially
Blink Dagger and
Eul's Scepter of Divinity, making Doom a nightmare to deal with as Puck.
* Doom can completely shut down Dazzle through Doom, as it prevents him from casting his abilities and, by extension, gaining Bad Juju stacks.
* Infernal Blade's damage is calculated by a percentage of maximum health, meaning that it will hurt Axe more than most normal attacks, negating some of his durability.
* Doom can pick up several different abilities from neutral creeps using Devour, some of which can be annoying to Axe.
* Mud Golem, Dark Troll Summoner, Harpy Stormcrafter, Satyr Mindstealer or Satyr Tormenter are good examples.
* Doom's naturally low attack speed makes Counter Helix less likely to proc, and his high base health allows him to take a few Helixes with no danger.
* Doom makes Axe less disruptive, preventing him from using his skills or items. At level 25, there is a branch of the talent tree that makes
Doom apply Break, allowing Doom to disable Counter Helix, making Axe effectively useless for a lengthy duration.
Additional:
* Infernal Blade deals scaling damage and is useful against high HP targets such as Axe.
* Doom has low attack speed because of his high Base-Attack-Time, poor agility gain and limited attack-speed granting items which are commonly built. This means Doom will trigger Counter Helix less often and thus is an unideal target for initiation.
* Doom has naturally high HP so it takes longer for Doom to be brought down to the killing threshold of Culling Blade.
* Axe is highly reliant on his abilities and items to be effective during a fight. Without the usage of Berserker's Call and
Blink Dagger due to
Doom, Axe offers very little in the way of damage, effectively removing him from a fight.
* Corrosive Haze provides True Sight on its target, exposing Bounty Hunter's position regardless of Shadow Walk.
* Guardian Sprint gives a very high movement speed bonus, allowing him to chase Bounty Hunter even if Slardar is tracked.
Additional:
* Bounty Hunter's Shadow Walk is rendered useless with Corrosive Haze and makes Bounty Hunter an easy target for Slardar and his team.
* With armor items like Solar Crest or
Assault Cuirass combined with Bash of the Deep, Slardar can easily tank the
Duel, If not dueled himself, he can drop
Legion Commander's armor during duel and/or buff his teammate and save them, leaving her only the choice of dueling supports which can also be saved with fast Blink into Slithereen Crush.
* Both Infernal Blade and
Doom can be used to disable Bane while he is channeling Fiend's Grip.
* A similar effect can be achieved by using Devour on {U:Centaur Conqueror}, which will give him access to
War Stomp.
* Doom applies a basic dispel upon cast, so it can remove
Guardian Angel.
* Casting Doom on Omniknight will also prevent him from healing allies with
Purification, or casting buffs like
Repel and
Guardian Angel, basically turning him into a harmless creep.
Additional:
* Doom turns Omniknight into a walking creep, or completely takes out his buffed cores, also removing Heavenly Grace and Guardian Angel in the process.
* With Devour used on Satyr Banisher, Doom will have access to Satyr Banisher's
Purge, which will allow him to remove Heavenly Grace and Guardian Angel.
* Tinker is heavily dependent on his abilities and Doom prevents him from using any of them.
* This becomes even worse if Doom chooses the level 25 talent {ValueColor:1|Doom applies Mute|25tal} {Symbol:Talent}, which will prevent Tinker from using items such as Blink Dagger.
Additional:
* Tinker is heavily reliant on casting his spells and Doom can disable all of his abilities and items. An
Aghanim's Scepter only makes it harder for Tinker to survive.
* Infernal Blade deals scaling damage and is useful against high HP targets such as Elder Titan. It also can interrupt Echo Stomp if quick enough.
* Doom has very low base armor and naturally high HP, so he isn't significantly affected by Natural Order.
* Doom with the {ValueColor:1|Doom applies Break|25tal} {Symbol:Talent} talent can be useful against heroes with troublesome passive skills while also disabling them for a long time:
Phantom Assassin,
Enchantress,
Huskar,
Underlord.
* Doom with the {ValueColor:1|Doom applies Break|25tal} {Symbol:Talent} talent can be useful against heroes with troublesome passive skills while also disabling them for a long time:
Phantom Assassin,
Enchantress,
Huskar,
Underlord.
Additional:
* Devour can easily eat creeps controlled by Enchant, limiting her ganking potential.
* Doom reduces the amount of healing received by Enchantress and her allies from Nature's Attendants. In addition, when Doom chooses the
Doom applies Break talent, it can also disable Untouchable.
* Heroes with silences: Puck,
Doom,
Riki.
* Slardar can attack through Plague Wards and gain
Bash of the Deep charges, and
Templar Assassin can spill
Psi Blades through Plague Wards too.
* Slardar can chase Dragon Knight down with
Guardian Sprint and stun him with both
Slithereen Crush and his passive
Bash of the Deep. He can also use
Corrosive Haze to whittle Dragon Knight's armor.
* Heroes with the ability to heal allies will not be able to heal heroes affected by Doom:
Chen,
Dazzle,
Io,
Oracle,
Omniknight,
Witch Doctor,
Winter Wyvern,
Abaddon, etc.
* Supports with useful teamfight or contribution spells will be helpless against Doom: Dazzle,
Oracle,
Warlock.
Additional:
* Doom will not only prevent Warlock from casting his abilities in team fights, but also it reduces the healing from Shadow Word.
* Devour allows Doom to acquire a stun from neutral creeps, allowing him to interrupt Upheaval without having to use
Doom.
* Silencer's
Global Silence and
Doom's
Doom makes Earthshaker temporarily useless.
* Heroes with the ability to heal allies will not be able to heal heroes affected by Doom:
Chen,
Dazzle,
Io,
Oracle,
Omniknight,
Witch Doctor,
Winter Wyvern,
Abaddon, etc.
* Heroes with the ability to heal allies will not be able to heal heroes affected by Doom:
Chen,
Dazzle,
Io,
Oracle,
Omniknight,
Witch Doctor,
Winter Wyvern,
Abaddon, etc.
* Heroes who often build Linken's Sphere:
Weaver,
Morphling,
Medusa.
* Weaver relies on Shukuchi to escape and kite enemy heroes. Slardar's Corrosive Haze lowers armor and reveals Weaver, who is already a very frail target.
* Weaver usually builds Linken's Sphere, Corrosive Haze can be used to pop the spell block, additionally the level 25 undispellable talent will prevent Weaver from removing Corrosive Haze with
Time Lapse, allowing allied heroes to use their abilities on Weaver.
Additional:
* Corrosive Haze lowers armor and reveals Weaver during Shukuchi, who is already a frail target. In addition, Weaver usually builds
Linken's Sphere, and
Corrosive Haze can be used to "pop" the spell block. His level 25 talent can also make Corrosive Haze undispellable by Time Lapse, which puts Weaver in an even worse situation.
* Guardian Sprint can dodge Weaver's bugs with the movement speed bonus.
* Enigma can be a perfect counter-initiator with his ultimate. A perfectly timed Black Hole will turn the tide of any initiation, especially from heroes like; Spirit Breaker,
Legion Commander,
Axe,
Puck, and
Slardar.
* Doom pierces spell immunity and can prevent Enigma from casting any spells or using items until the duration of the spell depletes, as well as cancelling a
Black Hole.
* While Doom can be blocked by a
Linken's Sphere, which is a common item on Enigma,
Aghanim's Scepter upgraded
Doom allows Doom to cast Doom on himself to affect enemies near him, and if Doom can combine this with
Blink Dagger, he will be able to jump on Enigma while he is channeling
Black Hole.
Aghanim's Scepter upgraded
Doom can also cancel
Black Hole if any of Enigma's allies affected by
Doom gets too close to him for it's duration, ignoring both,
Black King Bar and
Linken's Sphere.
* Tidehunter's
Kraken Shell dispels Corrosive Haze and Bash of the Deep's stun if enough damage is taken.
Anchor Smash and Kraken Shell's damage block also reduces Slardar's damage.
* Infernal Blade deals scaling damage and is useful against high HP targets such as Tidehunter.
* Doom prevents Tidehunter from casting his
Gush,
Anchor Smash and
Ravage, making him useless in team fights.
* If Doom chooses the Level 25 talent {ValueColor:1|Doom applies Break|25tal} {Symbol:Talent}, he can also disable Kraken Shell, reducing his survivability.
* Slardar does not do well against multiple targets, as his only way to damage multiple targets is Slithereen Crush.
* Meepo's Earthbind will root Slardar, making him unable to chase/escape for the time being. Also,
Poof's low cooldown and high damage can burst Slardar down rather quickly.
* Heroes who can stun multiple units at once: Dark Willow,
Spirit Breaker,
Slardar,
Invoker, and
Tidehunter.
* Besides Lone Druid and
Meepo, Doom is potentially good versus every hero since Doom will render any hero helpless for up to 16 seconds. This is particularly true for fragile heroes that heavily rely on mobility to stay alive.
* Illusion heroes like the aforementioned Phantom Lancer or
Naga Siren, or heroes that tend to buy
Manta Style, like
Luna or
Juggernaut, will give Slardar a hard time, as his damage is single-targeted.
* Heroes that can keep Luna locked down for a long time can be a threat (she is very item and spell dependent): Faceless Void,
Legion Commander,
Doom.
* Heroes without blink mechanisms or spell immunity will have a hard time positioning against Pit of Malice:
Sven,
Tiny,
Wraith King,
Dragon Knight,
Meepo,
Doom,
Bounty Hunter,
Dark Seer,
Undying,
Alchemist,
Legion Commander.
* Doom with the {ValueColor:1|Doom applies Break|25tal} {Symbol:Talent} talent can be useful against heroes with troublesome passive skills while also disabling them for a long time:
Phantom Assassin,
Enchantress,
Huskar,
Underlord.
Additional:
* Infernal Blade does damage based on percentage health, and is useful against high health pool hero like Underlord.
* Doom can prevent Underlord from spamming his abilities and most important is to prevent him from using Fiend's Gate to escape.
* Due to the nature of the hero, Sniper is typically situated in the back of the fight, potentially making him a difficult target to initiate on and fight.
* Sniper is largely a right-click hero, and as such isn't as an effective of a Doom target as other heroes.
* Thanks to Shrapnel and
Headshot, Sniper is able to effectively 'kite' Doom, preventing him from closing the distance between the two.
* Slardar can use Guardian Sprint with
Blink Dagger or
Shadow Blade to get close, and
Slithereen Crush will stun Sniper and slow him, making him vulnerable to Slardar's teammates.
* Corrosive Haze lowers Sniper's armor and makes Sniper's
Shadow Blade useless, easily killing him with a few attacks.
* Abaddon can cast Aphotic Shield on any of his allies to immediately dispel Corrosive Haze and/or the stun and the slow components of Slithereen Crush.
* All of Slardar's debuffs are also removed if Abaddon's Borrowed Time triggers.
* Doom will make Abaddon unable to use Mist Coil, Aphotic Shield, and the active component of Borrowed Time, also upgraded with
Aghanim's Scepter can break Curse of Avernus and the passive component of Borrowed Time ,which means his allies could be easily disabled or killed.
* Any heroes with low mana pools will die quickly or even instantly to Sanity's Eclipse: Doom,
Phantom Assassin,
Troll Warlord.
* Any heroes with silences can negate the majority of Outworld Destroyer's damage output: Death Prophet,
Night Stalker,
Drow Ranger,
Doom .
To start select enemy heroes in the field above. It's intended to be used with multiple heroes. The more enemy heroes you provide the better results you will get.
This website was made to help you in pick stage of online game Dota 2. It calculates rating for each possible counterpicks based on tips from web-based database made up entirely of user contributions Dota 2 wiki.
You will get the list of recommended hero counters with a list of tips written by Dota 2 wiki contributors explaining why it's good against the particular hero. In comparison to other similar websites, which show only rating based on average hero win rate from dotabuff or similar service.
Take it with a bit of grain of salt, especially if the recommendation has a low rating (<= 1), some heroes
may win a lane in an early game but would lose in late game (and vice versa). That's why sometimes
you could hero names appearing as a counter and as being countered, as on image:
You can also add your own tips, update old data and fix mistakes by editing page on Dota 2 Wiki (it works like Wikipedia - anyone can contribute, you don't even need to register) these edits will appear on this website automatically (data is updated several times per week).
Right now there is no app/overlay that will detect picks automatically (like overwolf dota plus or become the gamer), instead, you can open web version in a steam in-game browser or use mobile version on your smartphone.

Slardar
* Phantom Lancer's
Doppelganger has a low cooldown and applies a basic dispel on PL, making it hard to keep Corrosive Haze on him.
Manta Style which provides another basic dispel to remove Corrosive Haze with.
Diffusal Blade to quickly build up illusions while draining Slardar's mana.
Phantom Rush outruns Guardian Sprint, forcing Slardar to Blink away or use Slithereen Crush defensively to avoid being killed.

* Besides Slithereen Crush, Slardar does not have another way to deal with illusions and has a low mana pool, which allows Phantom Lancer with

Doom
* Phantom Lancer's illusions can make it difficult to Doom the real hero. Should Doom figure out the real hero, the illusions can make it difficult to cast any abilities, as their hitboxes can be used to body-block the real Phantom Lancer.
Diffusal Blade carrier. With it, he can quite easily deplete Doom's already poor mana pool, potentially making him unable to cast his abilities to escape, retaliate or heal.
* Phantom Lancer is an ideal
* Doom lacks any effective ability to clear waves of creeps and illusions, as the vast majority of his abilities are single-target. Without an answer, Doom may find it difficult to deal with Phantom Lancer's presence.
